Текст на картинке:
"Ты не можешь не плакать, если режешь лук жевательной резинкой. Ты не можешь не плакать в любой другой ситуации Пока не перестанешь быть таким маленьким неженкой."

Должно быть, это знаменитый английский юмор :I'm_thinking:

У меня немного по-иному получилось

Pirx 27.01.2020 18:56

Да можно и по-другому, смысл-то понятен...
Мне непонятно другое: чего это они так? Им не нужны хорошие моды? А Василий делает хорошие моды. Я, например, предпочитаю летать на переделанных им самолетах, потому что они объективно лучше, и приобретают индивидуальность. Допустим, на SAS этого могут не знать, но зачем же с ходу отбивать человеку желание? Или я чего-то крупно недопонимаю :I'm_thinking:

Может, мы как раз смысл не понимаем? У Ивана узина бы спросить..

Вот картинку нашёл - как раз про мои "модопоправляния".

Flies good! May I ask,what do those 2 values mean? Thanks.

To put it bluntly, he's calling Vasya a little bitch because nobody replied to his post.

Кому нужен Хурик с Даймлером под 4.10.1 - пожалуйста(!!!), в архиве ниже. :rolleyes:
Фикс высыпать в оригинальный мод. :ok:

These parameters characterize the flow of the wing.
The thin wing should have little difference between these parameters.

Ok thanks, so how did you come up with those values?

Through many tests over several years.

So that's a 'universal' setting then. What about laminar flow? Because just because there are big radiators hanging from the wing, engine nacelle, etc., doesn't necessarily mean big drag numbers.

This is the reference realistic aerodynamic data of the aircraft.

** CyCritH_0 1.29 - Cy 1.29 lift (in English often Cl) in direct flight at a critical angle of attack

** CyCritL_0 -0.69 - Cy -0.69 lift (in English often Cl) in inverted flight at a critical angle of attack

In IL-2, often well-realistic reference data.
But sometimes the correct realistic data does not work well.
The flight model is not perfect in IL-2, often it is necessary to conduct experiments.

For each plane I calculate my parameter.
I rely on the power of the engine, also look closely at the drawings - profile, wing narrowing, thickness and other parameters.
Setting up tx for each individual aircraft requires some calculations and several tests.
If there are polars of the original, then tx comes out of the first test.
The speed difference is 1-3 km.
Mig-3 flew with his TTX from the first time.
For other models it is necessary to correct different figures in fm.
This is to bring the behavior of the virtual plane closer to the original.
-------------------------------------------
This is my hobby in life.
Someone is fishing or climbing high mountains, and I like to set up virtual planes.

Ahhh so it takes the cross section of the wing. If the wing top / wing bottom are almost the same shape, the values should be closer to equal. Wing top / wing bottom, curved vs flat respectively, the greater the spread of the values. I understand now, thank you.

To put it simply, yes you are right.
But aerodynamics is a very complicated thing.
A real plane has many more interesting parameters.
The flight model in IL-2 is greatly simplified and NOT perfect!

Yes very complicated in real life vs game. Is prop wash modeled? It has a very big effect on flight performance. Even exhaust dumps. On the Spitfire for instance, having the dumps point towards the back (rather than angled downwards) netted a 10 mph gain with ZERO increase in horsepower!

What is it ? The language barrier prevents you from understanding.

As far as I know, in IL-2 there is no simulation “Even exhaust dumps” for piston internal combustion engines

As far as I know, NO.

1.There is propeller torque.
2. 2. There is a draft(thrust) of the propeller..

This is similar to the Meredith effect.
